well not sure how they will repair it,, but as it is that 20k nutaku gold 5* gacha gives instead of 150 rainbow medals 300 ( 150 as rolled and 150 in mail)

and 3 + 7 + 80 = 100 their math ...

from 5 rolls i got only kerria (already had 3 slots on her)

edit: fixxed already.. and "bonus" medals gone x(
